Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
If you have a number of decayed teeth then swelling on face can be
dental abscess formation.
Swelling in throat can be due to infection spreading to throat.
Similar symptoms can be due to
allergic reaction, but it looks most probably due to dental infection.
So my suggestion is to consult an Oral Physician and get evaluated and a thorough clinical evaluation and investigation like
x ray can help in confirmation..
You can be advised a course of antibiotics like
Augmentin and anti inflammatory painkillers like Ibuoprofen.
Do warm saline gargles and antiseptic mouthwash gargles.
Do cool compresses over the cheek.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Honey Arora
